To all whom it ma concern."

Be it known that I, SmRwIN Cour, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Teaching Devices, of which the following is a specification.

My invention relates to the art of teaching, and the object thereof is to provide means by which an exercise may be presented to a large .body of pupils in such manner that each one ma have the benefit of the exercise as an in ividual; that the errors made by him only shall be brought to his individual attent1on for study and correction, and that the work which each pupil does after the first presentation of an exercise to him shall be limited to the portions in which his errors occurred. I also provide a standard reference and check sheet with each original exercise and the corresponding repeat and exercise blanks. Each pupil is thus enabled to correct his own exercise and record his errors, While at the same time studying the correct form concerning which" his error occurred. And in so doing the teacher is provided with complete data of the work of the class and of the individual pupils comprising the same.

I have illustrated the principles ofmy invention by reference to struction in spelling. In the drawings:

Figure 1 shows a front view, the several exercise blanks being in parts broken away;

Fig. 2 is a cross section thereof on the line 2-2 of Fig. l. V v

Further describing my invention with reference to the drawing: A is a standard correction or check sheet, on which in column a is printed the list of words phonetically spelled, which are to be given out, and which constitute the exercise. Such words for convenience may be numbered in column The correct spelling of each word is shown in column a. At the extreme right of the check sheet are a number of checking columns 1, 2, 3, etc., for the use as hereinafter to be described. A multiplicity of exercise sheets 1', 2, 3, etc., may be attached as indicated at 5 to the check sheet by adhesives or other suitable means, so that, in the order shown, they are superimposed upon each other and upon the check sheet. Such exercise sheets each contain the list of words a device for inshown in column a of the standard or check sheet, and the numbers shown in 6 of the standard sheet, but that portion corresponding to column 0 is left blank, giving a space in which the exercise is to be written. The exercise sheets preferably are narrower than the check sheet upon which they are im posed, and to which they may be attached as shown at 5, only extending as far as the check columns at the right thereof.

The device constructed as described may be used in class work, one set of blanks being appropriated and iven out to each pupil at the beginning 0 the first exercise. It may also be used for private study or for correspondence instruction, if desired; but, by way of explaining its use, a classroom exercise will be assumed.

Each pupil on taking his sheets will write on exercise blank numbered 1, opposite the list of words at the left, the correct spelling of each as far as he is informed. When all the words are written the exercise leaves are turned back and he compares what he has written with the corresponding words in column 0 of the standard sheet. When a word is found misspelled insuch first exercise written upon the sheet designated as 1 the pupil places a check mark in column No. 1. Upon such comparison and check being completed column 1 indicates the number of words and the particular words which have been misspelled. These words alone are the only ones which it is necessary for the pupil to study and only so much of his time as is necessary for this study is required. The next exercise is written in like manner as before upon the exercise sheet numbered 2, only such words being written as the check marks in column 1 indicate were misspelled. This the pupil does in the light of the study which he has placed upon this particular portion of the list, and when his work is complete he checks the words which he has written by reference to column c on the standard sheet. The pupil should'of course find comparatively few misspelled words, and these alone are the ones which are to have further study. This portion of exercise being repeated upon sheet 3' is again checked, if any misspelled words are found in column 3.

In further detail referring to word numbered 12 in the drawing: it will be seen by the check mark in column 1 that at the first a the columns are totaled, out of twenty words,

constituting the exercise, ten were misspelled at-the first test, four only were misspelled at the second test, and one onl at the third test. All the words of the 11st which were but one, it is clear misspelled having been eliminated that a very slight amount originally of study on the remaining wor in perfection or 100% correct spelling.

Likewise the exercise may consist of unpunctuated reading matter in which to 1nsert the necessary punctuation marks, while the check sheet will show the same matter with the punctuation marks correctly 1n- I sorted. in the various checking spaces opin which the pupil wi l correct, while the check would be placed in the exercise to of a plurality posite each line the number of errors in that line may be recorded, so that an addition of the total number of errors in each column of checking spaces will show the total number of errors made in preparing the exercise on the corresponding exercise sheet.

Or the exercise ma consist of sentences be given a choice of two grammatical forms, one correct and one incorrect, to cross out the one which is insheet will show the same exercise with the incorrect grammatical form crossed out. Opposite each sentence incorrectly marked a checkmark the colunm of blank spaces corresponding .to the number of the exercise sheet Or-the device may be applied to an other subject for study and practice in using the right form.

I claim: I

1. In a teaching device; the combination oi a plurality of exercise sheets containing be corrected and adapted to receive corrections, with a check sheet containing the exerclse in corrected form and check columns not less in number than the exercise sheets associated therewith.

2. In a teaching device; the combination of superimposed exercise sheets attached together and containing the exercise to be corrected and adapted to receive corrections, with a check sheet containing the exercise in corrected form and check columns corresponding in. number to the exercise sheets associated therewith.

3. In a teachingdevice; the combination d will result to the exercise blanks,

instant of a multiplicity of; exercise blanks each containing matter indicative of the test work to be done and blank spaces for said test work, with a correction and check sheet comprising the said matter indicative of the test work to be done, thesaid test work in corrected form and check rulings corresponding to the exercise blanks and extending therebeyond.

d. lln a teaching device; the combination or amultiplicity of exercise blanks each containing matter indicative of the test work blank spaces for said test to be done and work, with a correction and check sheet comprising the said matter indicative of the test work to be done, the said test work in corrected form and check rulings corresponding said exercise sheets being imposed on each other and on the check sheet to hide the latter with the exception of the said check rulings;

5;. In a teaching device; the combination of an exercise blank having mater indicative of the test work to be done, and spaces in which to place the said work, a duplicate blank or blanks attached thereto for repeat work, and a check sheet having matter indicative of the work to be done and the correct form thereof attachedto and normally hidden by the original and duplicate blanks, and fa projecting portion having columns corresponding to the original and duplicate blanks for checkand record of the work done thereon/ I 6. In a teaching device; the combination of a plurality of exercise sheets containing in columnar form the several items of the exercise to be corrected, and a blank column with a check sheet containlng the several items of the exercise in the same relative position as on vided with checkcolumns correspondmg in number to the exercise sheets used.

c 7. In a teaching device; the combination of a plurality of exercise sheets containing in columnar form a list of misspelled or phonetically spelled words and spaces for writing the same in correct form opposite thereto, with a check sheet containing in columnar form the list of said words as corrected and provided with check columns correspionding in numberto the exercise sheets use In witness whereof I have hereunto subscribed my name this 5th day of February, 1918, at New York, county of. New York and State of New York.
